c) if the students didn't do the test, they would fail the subject
d) would you help me if i asked you?
e) if he had a dog, he'd be happier​

Answer 1

primeiro condicional = oração if (oração subordinada) está no tempo "simple present", enquanto a oração principal está no tempo "simple future" (que usa o auxiliar "will")

portanto, a única frase que está obedecendo essa estrutuda do first conditional é a letra B

b) Marcos will (simple future) buy a bigger house, if he marries (simple present na oração "if") her
